Making crab feed from potato

The potato is used to produce crab feed, which has wide raw materials, low cost, good palatability and rich nutrition. The crab likes to eat and grow. At the same time, the preparation method of the feed is relatively simple, and can be produced mechanically or manually, so that the potato crab feed has wide application value. The key points of processing and feeding technology are described as follows for reference by aquaculture households.

Process flow: material selection → cleaning → cutting → cooking → crushing → ingredients → molding → drying.

Processing technology: (1) Selection of materials. Potato without diseases and insect pests, germination and mildew is selected as raw material. Choose more nutritious spring potatoes. (2) Cleaning. Remove potato skins mechanically or manually and rinse with water. (3) Cut into pieces. Cut the potatoes into small pieces of uniform size so that they are cooked evenly. (4) Cooking. Cook potatoes in stainless steel pan or aluminum pan or steamer until they are ripe. Cool. (5) Broken. After cooling, the potatoes are picked up in time and broken into paste or thick paste by mechanical crushing or manual stirring. (6) Ingredients. In order to enhance palatability and improve nutritional components, the above ingredients can be added into the crushed potato according to the proportion of 100g salt, 50g essence, 100g ferula and 200g vitamin C per 100kg potato, and stirred uniformly in time. (7) Shaping. Machine or hand made into small cubes or granules of suitable size. (8) Drying. Dry or dry in time, and store in sealed plastic bags.

Feeding method: adult crabs are fed 2-3 times a day, young crabs are fed 1-2 times a day, but they must be fed again when the feed fed last time is finished. Feed should be put in a clean place, it is best to set up a feeding table to feed.
